  • Blast-resistant features are those that enable a vehicle to mitigate the effects of an explosion.
  • Numerous exemplary embodiments of vehicles having one or more blast-resistant features are described below.
  • Armored vehicles, and other vehicles, described by the exemplary embodiments that have these features are not limited to only those embodiments, however.
  • exemplary embodiments may be used for other types of vehicles or machines outside of the defense industry.
  • the exemplary embodiments may be sized or shaped differently, in any suitable manner, and may be adapted to add components not described, or to remove components that are.
  • One possessing ordinary skill in the art will appreciate the use of the exemplary embodiments for purposes and benefits in alternative forms and industries, depending upon specific design needs and other considerations.
  • FIGS. 1-8 illustrate embodiments for vehicles, particularly armored vehicles, that are efficient in mitigating mine or IED blasts in that these embodiments may satisfy one or more of three above-mentioned ways to manage the energy and impulse generated from a blast.
  • FIG. 1 illustrates an exemplary hull 100 for a vehicle, such as an armored vehicle.
  • the hull 100 may generally be W-shaped, or alternatively referred to as double-V shaped or double-vertex shaped.
  • the hull 100 may comprise two vertex structures 110 .
  • Each vertex structure 110 may comprise an inside-inclined wall 114 , and an outside-inclined wall 116 .
  • the inside inclined wall 114 and outside inclined wall 116 may be welded together.
  • Each vertex structure 110 may extend axially and substantially parallel to the centerline of the hull 100 from the rear of the hull 100 to the front of the hull 100 .
  • the two vertex structures 110 may be directed downward such that the apex 120 of each vertex structure 110 will be the lowest point relative to the ground.
  • the hull 100 shown in FIG. 1 may extend axially along the entire length of a vehicle or extend axially along a part of the entire length of a vehicle. In other words, the hull 100 may be used on any vehicle configuration, and one of ordinary of skill in the art can readily determine the appropriate axial length for the hull 100 .
  • the angle ⁇ of each vertex structure 110 may be determined based on a particular vehicle configuration and the intended purpose of that vehicle. In an exemplary embodiment, the angle ⁇ of each vertex structure 110 may be within a range of 30° to 100° but preferably within 45° to 90°. While these values for angle ⁇ are preferable, a double-vertexed hull may be fabricated with any suitable angle ⁇ and still maintain the desired structure and function as described herein. In an exemplary embodiment, the angel ⁇ for each vertex structure 110 may be substantially equal. Of course, in alternative embodiments, angel ⁇ for each vertex structure 110 may be dissimilar.
  • the angle ⁇ 0 for each vertex structure 110 may influence the maneuverability and blast protection capabilities of a vehicle.
  • a vehicle having a W-shaped hull designed with a narrower angle ⁇ will have a higher center of gravity and/or smaller standoff but will better counteract the blast impulse from an explosion.
  • a vehicle having a W-shaped hull designed with a wider angel ⁇ will have a lower center of gravity and/or higher standoff but will have diminished capabilities to counteract the blast impulse from an explosion.
  • This description is meant only to describe the countervailing factors for W-shaped hulls.
  • any suitable angle ⁇ for each vertex structure 110 may be used.
  • the hull 100 to have two vertex structures 110 , compared to a hull with a single vertex structure, will reduce the vertex angle ⁇ by half for a given hull width. This, in turn, will increase the angles of the inclined-inside walls 116 relatively to the hull's vertical axis.
  • These features may result in advantageously increasing the angle of attack between a blast wave and the hull 100 , thereby causing a lower received pressure load while simultaneously creating space at the center of the hull 100 (described below) to incorporate the driveshaft and the differentials, which are shown in FIG. 1 .
  • the angle of attack between a blast wave and the hull 100 depends on the location of an explosion.
  • the hull 100 still provides advantageous features because it provides for a larger distance between the explosion and the hull 100 , which further mitigates the impact of the blast.
  • the W-shaped hull 100 may also have a high moment of inertia about the longitudinal axis, and the bending stiffness of the hull 100 may be improved relative to non-W-shaped hull. Specifically, the bending stiffness may be high across the lower structure of the hull 100 , resulting in the hull 100 being able to mitigate any localized deformation after an explosion when the blast wave propagates throughout the entire structure of a vehicle. In other words, the W-shaped hull 100 may provide a high-bending stiffness during an explosion about its y-axis. This stiffness may allow for the W-shaped hull 100 to transfer localized deformation energy and momentum from the blast into a global response, thereby reducing localized damage. Quickly and effectively transferring blast energy from a localized area, which is of low mass, to the entire vehicle structure, which is of high mass, may lower the velocity of local plates, thereby reducing damage to the hull 100 while conserving the momentum.
  • the vertex structures 110 may be located approximately at the quarter-line of the hull 100 relative to its width.
  • a hull's quarter-line may be a particularly vulnerable area for a vehicle during an explosion because, typically, there may be a flat horizontal or non-angled plate covering this area of a vehicle. A flat plate may collect a high impulse from the blast and result in high deflection.
  • the vertex structures 110 are not limited to being located at the quarter-line of the hull 100 relative to its width.
  • One of ordinary skill in the art can adjust the placement of each vertex structure 110 as necessary and/or desired. That is, in other embodiments, the vertex structures 110 may be located at other places relative to a hull's width and may or may not be symmetric.
  • the apex 120 of the vertex structures 110 may generally be between dimensioned and positioned such that a vehicle manufactured or retrofitted with the hull 100 may be able to adeptly traverse and maneuver over terrains likely to be encountered by a vehicle. To achieve this, a vehicle equipped with the W-shaped hull 100 may therefore maintain any suitable ground clearance depending on a vehicle's configuration and intended purpose.
  • each outside inclined wall 116 extends upwardly from the apex 120 and into a sponson 112 .
  • the sponson 112 may form the top portion of the W-shaped hull 110 .
  • a transition angle ⁇ may be formed between each outside inclined wall 116 and each sponson 112 .
  • the transition angle ⁇ may be of any suitable dimension depending on the vehicle configuration. In an exemplary embodiment, transition angle ⁇ between the outside inclined wall 116 and the sponson 112 may provide for lower deflection.
  • the outside inclined wall 116 and the sponson 112 may be formed from a one-piece construction in an exemplary embodiment but is not limited thereto.
  • a single sheet or plate will be bent to form this lower part of the hull 100 , thereby eliminating the potentially vulnerable area between the sponson 112 and the outside inclined walls 116 .
  • This type of construction may result in a geometric transition between the sponson 112 and the outside inclined walls 116 potentially able to minimize the stiffness gradient at this location in the hull 100 .
  • the deformation of the hull 100 may be more uniform and evenly distributed across the area.
  • the W-shaped hull 100 may not comprise a sponson 112 while still maintaining the double-vertex shape.
  • the double-vertex shaped hull 100 are also contemplated herein.
  • the outside inclined wall 116 may be replaced with an entirely vertical wall or be constructed from two or more panels where those panels could be straight, angled, or a combination of both.
  • the present description contemplates any hull configuration that uses double-vertex shape notwithstanding what the precise dimensions of the panels to form the vertexes.
  • the hull 100 may comprise a concave structure 118 .
  • the concave structure 118 may be located between the two vertex structures 110 . Still referring to FIGS. 1-6 a , which illustrates an inverted W-shaped hull, the concave structure 118 may be formed by the two inside-inclined walls 114 and have a substantially flat surface 122 .
  • the concave structure 118 like the two vertex structures 110 , may extend axially from a front portion of the hull 100 to a back portion, with the centerline of the concave structure 118 being coplanar with the centerline of the hull 100 , in one embodiment.
  • the concave structure 118 may extend along the entire axial length of a vehicle or only along a portion of the axial length. In an exemplary embodiment, the concave structure 118 may maintain a necessary ground clearance depending on the vehicles configuration and its intended purpose.
  • the concave structure 118 may create a space for other vehicles components, including the driveshaft and differentials. Creating a space for vehicles components may also provide desired access to a vehicle's mechanical components for desired maintenance. In addition, these mechanical components may be designed not to impact the hull 100 during a blast event.
  • the concave structure 118 may comprise multi-part piece having one or more panels, although a single piece construction is preferred. The concave structure 118 may also be layered with another protective panel or other blast-resistant features.
  • the hull 100 may comprise one or more notches 130 , depending on the number of wheels a particularly vehicle might have.
  • each of the vertex structures 110 may have a plurality of notches 130 to accommodate the wheel axles 132 .
  • Wheels may be mounted onto a single axle that extends across the full width of the hull 100 and through the notches 130 in the vertex structures 110 .
  • An axle may be any suitable shape and mounted in any suitable way. Further, one of ordinary skill in the art can determine the appropriate suspension system to use based on the vehicle configuration.
  • hull 100 and its components can be used for various materials, depending on system requirements on space claim, weight impact, budget-cost constraints, and manufacturing techniques and equipment. Possible, non-limiting materials that can be used for the hull 100 and its components include steel, aluminum, titanium, ballistic steel, ballistic aluminum, ballistic titanium, composites, and so on, or a combination of materials. Moreover, the thickness of the hull 100 can vary as necessary and/or desired.
  • the hull 100 can be designed and dimensioned for a variety of wheeled vehicles, including High Speed, Agile Light Vehicles; Wheeled combat and Derivative Vehicles; Medium Transport & Support Vehicles; Heavy Transport Vehicles; and Tank Transporters. These vehicles may be 4 ⁇ 4, 6 ⁇ 6, or 8 ⁇ 8 wheeled vehicles, or have any other wheel configuration.
  • the hull 100 may also be used for vehicles driven by tracks, or a combination of wheels and tracks.
  • FIG. 8 shows an exemplary embodiment of a vehicle having a W-shaped hull.
  • the depicted vehicle may be a full-time four-wheel drive, selectively eight-wheel drive, light-armored vehicle.
  • the vehicle may provide for armored protection of the crew.
  • the W-shaped hull 100 may extend along the entire length of a vehicle or only along an intermediate length, which will be described in more detail below.
  • the hull 100 may generally be symmetric about the longitudinal centerline of the vehicle.
  • the W-shaped hull 100 may provide efficient mine-blast protection for a vehicle, without significantly impacting the vehicle's weight.
  • the W-shaped hull 100 may create a controlled directional deformation at a specific location on the hull 100 due to the hull's geometric attributes. Specifically, when an explosion occurs underneath a vehicle, a downward force may be produced on the surface 122 of the concave structure 118 , which may be a critical area for a vehicle because a vehicle's crew may sit directly above that location—i.e., the crew's feet may be positioned close to the hull's floor at that location. This downward force may counteract any upward deformation induced by the blast pressure. By counteracting upward deformation, the hull 100 may be able to mitigate vertical deflection.
  • the Lee Effect is a blast-deformation technique that relies on a structure's geometric properties.
  • the W-shaped hull is an example of one such structure that uses the Lee Effect.
  • the Lee Effect describes a structure using its own geometric attributes to create a downward force by depending on the lateral deformation induced by a blast on a connected part of the structure to counteract any vertical upward deflection caused by a blast-type load.
  • the blast shockwave and debris will first impact the inclined-inside walls 114 of the hull 100 structure first, pushing the inclined-inside walls 114 away in a direction that is normal to the plate.
  • the shockwave and debris will next impact the substantially flat surface 122 of the concave structure 118 because of its distance from the explosive device.
  • the surface 122 of the concave structure 118 will receive an upward force induced by the pressure, debris, and shockwave. But, as the inclined-inside walls 114 of the hull 100 begin to deform at a direction normal to their surfaces, a horizontal deformation component may be created.
  • This horizontal deformation component may create a downward force on the substantially flat surface 122 of the concave structure 118 —in part because these structures are connected structures and have a tendency to conserve volume—pulling the substantially flat surface 122 downward.
  • This downward action caused by the horizontal deformation component counteracts the upward force being exhibited on the surface 122 of the concave structure 118 .
  • This counteraction mitigates any vertical deflection of the concave structure 118 , reducing the injury to a crew when a blast event occurs.
  • the inclined-inside walls 114 deform, kinetic energy from the blast is transformed into strain energy of the material in the hull 100 , thus reducing any energy that is available to deform the plate and accelerate the hull 100 . It should be noted that some elastic recovery occurs at the deformed surfaces, which causes the inclined-inside walls 114 and the concave structure 118 to vibrate in a cyclic, synchronized manner.
  • the hull 100 initially deforms at the inclined-inside walls 114 of the hull 100 .
  • This deformation occurs underneath the crew floor and generally consists of lateral deformation and not vertical deformation. Therefore, the impact to the crew floor or the crew may be minimized.
  • the blast energy received by the hull 100 may be transferred into strain energy, thus reducing the available energy for global vehicle motion. As a result, the available energy associated with the acceleration of the vehicle and its crews is minimized. This will significantly reduce the Dynamic Response Index (DRI) value, hence improving crew survivability.
  • DRI Dynamic Response Index
  • the W-shaped hull is also designed to mitigate a blast if an explosive device is detonated between the centerline of the hull 100 and one of the outside inclined walls 116 .
  • the vertex structures 110 of the W-shaped hull are located at or near the quarter-line of the hull 100 .
  • the average angle of attack between the shock wave and the hull 100 may be maximized, which will reduce the pressure load on all surfaces of the hull 100 .
  • the hull 100 may have a heightened stiffness at the vertex structures 110 , further mitigating vertical deformation.
  • a crew floor (not shown) will be mounted inside of a vehicle and above the hull 100 .
  • the floor may run horizontal to the concave structure 118 of the hull 100 .
  • the floor may comprise any additional blast-resistant features, which further protect a crew during an explosion. Such additional blast-resistant features are known in the art.
